Я только что установил Ubuntu 18.04 (раньше использовал элементарную ОС) на своей Dell Latitude, в которой два монитора подключены через док-станцию DisplayLink. Мне удалось получить три экрана (экран для ноутбука + два внешних), работающих на Elemantary OS после установки драйверов DisplayLink с веб-сайта Dell. На Ubuntu 18.04 я не вижу внешних мониторов, хотя мне удалось установить драйверы DispplayLink.
Я пробовал с проприетарными драйверами NVIDIA (nvidia-driver-390) и с X.Org nouveau (xserver-xorg-video-nouveau).
EDIT: Я предполагаю, что Dell Драйвер DisplayLink не обновляется / работает с Ubuntu 18.04. Будет следить за http://www.displaylink.com/downloads/ubuntu
Другая проблема, возможно связанная: я могу загружаться только в Ubuntu, используя «Ubuntu on Wayland», по умолчанию Ubuntu просто подходит вернуться к экрану входа в систему после ввода пароля.
